The

hnr 22 cross strips or bars 25 are given a slight downward inclination toward their front edges Iby attaching the assembled screenreflector and particularly the band 23 within the rim or ring 16 at a slight inward angle toward the light 26. Said bars 25 are polished or coated so as to form reflecting surfaceswhich reflect the intercepted parallel rays of light from the parabolic re-` flector 11 downward upon the middle area in a broad flat shaft of light, though not nearly as strong as the shaft formed by the main parallel rays reflected from the parabolic reflector 11. or even the direct rays from the light 26 which shine downward immediately upon the roadway in front of the lamp. rl`he vision of the passerby or bystander is protected from the Ina-in central beam of light by means of the shield plate 27 which is attached to the vision protecting screen 17 immediately in front of the light 26.

` In the diagram shown in Figs. 4 and 5, the broad field in front of the pair of lamps 10 is divided into three overlapping areas A, B and C, portions of the areas A and B being broken away to bring the diagrams within the required dimensions for these drawings. The strength of the rays of light to these three areas are shown approximately by dotted lines. The areas A are farthest from the lamps, and the areasl C are immediately in front of the lamps, while the areas B intervene between the areas A and C. AS stated and showmhese areas overlap one another sufficiently o produce a cornparatively even light, though the areas A are lighted much more strongly by the reflected parallel rays from the parabolic 'refiector than either the areas B or C and the areas C are lighted by the direct rays which pass through the open lower portion 28 of the lamp. The intermediate area Bis lighted by the double reflected rays and the direct rays from the light 26.

v The slight downward inclination of the Vision protecting screen-reflector 17 causes its cross bars to intercept a certain portion of the parallel rays which are reflected from the parabolic reflector 11 thereby `giving said rays a second or double reflection downward upon the roadway in the intermediate area B assisting the direct ra s of light in the illumination of said in .rmediate area. thin to cause but slight obstruction of the rays of light and are placed sufficiently far apart to permit a wide clear lateral projection of the light thereby attaining the desired purpose of limiting the upward reflection.but .projecting a wide lateral field of light.

The light 26 is preferably an electric lamp in a. suitable lamp post 29 with wire connections 30 to the source of' electrical energy; the lamp 26 being adjustable in said holder so that it may7 be correctly adjusted as to position within the parabolic reflector 11 to reflect the rays of light in parallel alinemeut therefrom. The slight downward inclination of the strips in the path of a predetermined portion of the parallel rays of light makes use of the sheen or luster quality of said strips and enhances their reflective qualities. 'lrhe outwardly project-ing flange of the rim oi' ring 16 being clamped between the glass 1'9 and the flange 1l of the reflector 11 acts to hold or support the rim or ring 16 and thereby the screen 17, without danger of rattling or breakage.

I claim as new 1. In combination with a parabolic reflector, a. substantially semi-circular rim, and a series of spaced horizontal strips rigidly secured at their ends to the rim, the lowermost of said strips being bent upwardly at its center to provide an' approximate inverted V- formation.

2. In combination with a parabolic reflector, a screen having a substantially semicircular rim, and a series of spaced horizontal strips rigidly secured at their ends to the rim, the two lowermost of said strips being bent upwardly at their centers to provide an approximate inverted V formation, the apices of the said V-strips being superimposed and the apex of the up-permost strip being engaged with the adjacent upper strip, said V-strips providing a cross-bar for the bottom of the screen and also affording an addition to the reflected rays of' light.

In testimony whereof I have aflixed my signature in the presence of two witnesses.
